Deep Link Generator

Generate custom scheme URLs, Android Intent URLs, and iOS Universal Links for deep linking into your mobile app. Free, instant.

Last updated:

Firebase Dynamic Links stopped working on 25 August 2025, so this tool no longer generates them. For links that open an app and fall back to the web, use Universal Links (iOS) and App Links (Android) on your own domain, or a deep-link service such as Branch, AppsFlyer OneLink or Adjust.

myapp://open/product/123?ref=banner&utm_source=email
<!-- App Store / Play Store smart banner -->
<meta name="apple-itunes-app" content="app-id=123456789" />
<meta name="google-play-app" content="app-id=com.example.myapp" />

<!-- Universal link intent -->
<a href="myapp://open/product/123?ref=banner&utm_source=email"
   onclick="setTimeout(function(){ window.location='https://example.com/product/123'; }, 1500)">
  Open in app
</a>

How the Deep Link Generator works

The deep link generator builds correctly formatted deep link URLs for iOS and Android applications. Enter your URI scheme, host, path, and query parameters to generate custom scheme URLs, Android Intent URLs, and iOS Universal Link / App Link formats — along with a ready-to-use HTML snippet for embedding in web pages and marketing emails without writing the fallback logic manually.

Custom URI scheme links

Custom URI schemes take the form myapp://host/path?param=value. They are registered in the app's Info.plist (iOS) or AndroidManifest.xml (Android) and trigger the app when tapped. For example, twitter:// opens Twitter, mailto:// opens the email client. Custom schemes are simple to implement but have no fallback to the app store if the app is not installed — Universal Links solve this limitation on iOS.

iOS Universal Links

Universal Links use standard HTTPS URLs (e.g., https://example.com/profile/123) with an associated domains entitlement and an apple-app-site-association (AASA) JSON file served at /.well-known/apple-app-site-association. When the app is installed, iOS intercepts matching HTTPS URLs and opens the app directly. When it is not installed, the browser falls through to the regular web page — giving a seamless experience with no broken links.

Android App Links and Intent URLs

Android App Links work similarly to Universal Links using Digital Asset Links JSON at /.well-known/assetlinks.json. The intent:// URL format provides another option for Android-specific links: intent://profile/123#Intent;scheme=myapp;package=com.example.app;end. This syntax allows specifying a fallback URL, a package name for direct Play Store redirect, and Android-specific parameters not expressible in a plain URI scheme.

Testing deep links on device

On Android, you can test deep links from the command line using adb shell am start -a android.intent.action.VIEW -d "myapp://test/path". On iOS, xcrun simctl openurl booted "myapp://test/path" tests links in the simulator. The generator's output includes these test commands pre-populated with your configured link so you can copy and run them immediately during development without manual string construction.

Frequently asked questions

What is a deep link?
A deep link is a URL that navigates directly to a specific screen or piece of content inside a mobile app, bypassing the home screen entirely. For example, myapp://product/123 would open a specific product detail page inside the app. Deep links are used in push notifications, email campaigns, and social media ads to reduce the steps between click and conversion.
What is the difference between URI scheme and Universal Link?
A URI scheme (such as myapp://) is the traditional method — it works when the app is installed, but shows an error or falls back to nothing if the app is not installed. Universal Links (iOS) and App Links (Android) use standard https:// URLs — if the app is installed they open the app directly; if not, the browser opens the fallback website. Universal Links provide a far better user experience and are the recommended approach.
Can I still use Firebase Dynamic Links?
No. Google shut Firebase Dynamic Links down on 25 August 2025 and the links now return a 404 error. Use Universal Links (iOS) and App Links (Android) on your own domain, or a deep-link service such as Branch, AppsFlyer OneLink or Adjust, if you need links that open the app or fall back to the web and survive an install.
